That's fucking 99.9% of all genderbenders/swaps. Always fucking yuri. To the point that I have gotten bloody sick of it. (I did enjoy reading such stuff, but it just becomes so samey after a while)
Straight is fine once in a while for gods sake. He changed into a girl, his biological systems and brain should also be currently shifting (though tbf, women overall are a lot more likely to be bi than men, the more you know).
Either way, I am tired of the constant yuri paths. Nice to see a straight path once in a while. If you want pure yuri, go pick from hundreds of webnovels, western novels (forum novels, web novels there included), manwah (though genderbend is pretty rare there overall), manga, light novels and so on. Because they are in the hundreds.
Straight genderbender is a rarity.
